To all whom it may concern:

Be it known that we, LnwIs C1- IAEM Zwnanrme and SAMUEL A. GREEN, citizens of the United States, residing at Brooklyn, inthe county of Kings and Stateof New York, have invented certain new and useinl Improvements in Lite-Saving Devices, of

which the following is a specification.

This invention relates to improvements in life saving devices and relatesparticularly -to the construction of a. device the passenger car of which will be non-turning inwater fand whichwill be effectively ventilated.

One of-the objects of, the invention is the construction of asubmarine life saving boat .or device having a passenger car adapted to be held by force of gravity in a position holding'jthe mssengersvertical.4

. .Another object of the inventionis the construction of a. submarine boathaving a ventilating tube adapted to allow air and to prevent water entering the interior of the boat and adapted tooccupy a normal upright or substantially vertical position. ith the above and other objects in view the invention embraces certain combinations, constructions and arrangementsof .1n the tollowing specification and clearly illustrated the proved device.

.of the boat. F pelle'ropcr illiistratin'g the hold the closed and said accompanying drawings, inwhieh,

Figure 1 is atop plan view of the iniliig. 2 is a side elevation thereof. Fig. 2?. i571. detail perspective view 3 is a transversesectional.

2. Fig. 4 is a side elevation Fig. 5 is adetail oftheboat, Fi 6 is. ardetail elevation of the bow of the boat, Fig. 7 is a transverse seetionalview Fig. 8 is a detail of the proating' niechanisn'i and Fig. 9 is an end elevation ot the stern of the boat.

Referring to the accompanying drawings construction of he iniprovcd lifesaving, boat, shell of the boat which is preferably formed cylindrical and provided with tapering outer ends 2 and 3. The middle body POT." tion of the cylindrical shell is provided with observing and light" openings 'which are water sealed by glass disks 4. further provided 'with't'rap doors 5, which openings over the steps 6 normally doors are properly water sealed. Hooks 7 are located on the outer slightly deflected toward the tube 17.

1 denotes the outer he shell 1 is The forward endv of the boat is provided with a which is which encircles the end 250 as to allow the nose of the water spreader to rotate thereon. The water spreader serves to out the water in advance -01 the boat, so that the boat can move more easily through the same and the agitated .water will not interfere with the sight line or the light, which passes through the transparent forward end ofthe boat. A wire cage 10, having glass sections 11 is connected to the boat 1. This cage completely covers the front end of the boat 1 The inner end of the rod 12 is suit-' ably supported by braces or other mechani cal supports arranged in the boat 1. The outer end of the nose 8 is supported by a rod 12, which is in turn partly supported by the wire cage 10. The rear end 3 is provided with a circular wall 13, which is water sealed on the end 3 by a circular guide 14," which is provided with a packin 1.5. The lower end 16 of a ventilating tube 17 extends through a water sealed opening in cone-shaped nose or spreader 8,

thewall 13 and said lower end is flared out wardly and located within the passenger car 18, which is adapted to ride on the inner side of the boat shell wall, The upper end of the ventilating tube 17 is disposed at right angles to the lower end so that said upper end can be held above the water line, and for this purpose said upper end is made considerablyhigher than. the boa t. On the top of the upper end of the tube 17 a hood 19 is mounted. said hood being provided with a right angular iuner end 20, which is On the tube 17 is an auxiliary hood 21 having an outwardly deflected angular portion 92, which is spaced above the inwardly deflected angular portion 20 of the outer hood 19. so as to leave a space for the-passage of air tlmrel'ietween. The angular portion 20 of the hood 19 is provided with openings 23, whereby the water thrown into the hood ltl can escape therefrom. Air enters the tube 17 through the passage between the angular portions 20 and22- and passes downward into the lower end of the tube and thence intothe interior of the car 18, thus supplying any passengers therein with fresh air. On the tube 17 is suspended a bearing bracket 24, on which is journaled a proeonnected tl'iereto by a band. 9,

1 so that the boat can be peller shaft 25, which shaft carries a beveled gear 26 and a paddle wheel or other propeller 27. The gear 26 engages with a drive gear 28 on a-shaft 29 which extends inwardly of the car 18, and said shaft 29- is provided on itsinner end with a wheel 30,

having a handle 31 thereon, whereby the,

means of rods 36 and 37 the' outer ends of which are bent. The outer end of the rod 36 is bent at right angles to itself and the outer end of the rod 37 is bent rearwardly toward itself. This last end is passed through an eye 38 on the, end of the rudder 34 adjacent the end 3, and is provided with a head 39, whereby said end will not become disconnected from the rudder 34:. The

rod 36 is connected to the wall 13 and forms a pivot for the'rudder 34. and the rod 37 extends,inwardly of the boat and is provided on its inner end with an operating crank. 40, which is mounted for ope 'ation near the wheel 30 but so asnot to interfere with said wheel 30. \Vhen the crank L0 occupies the position shown in Fig. 6 the rudder will be held on plane parallel with the longitudinal axis of the boat.

The car 18 is inovably supported on the interior of the shell 1 so that when the boat is rotated by the waves or water the car will be held so that the passengers will be normally substantially vertical. F or this purpose the car is provided'with wheels or runners 41, which are pivotally supported on the outer side thereof and which. are adapted to ride on angular tracks -12, fixed on the inner side of the wall of the shell'l, and of a circular shape. The car 18 is provided with cushioned seats 43, for the comfort of the passengers.

The shaft 29 is divided at 44 and the ends thereof are provided with engaging gears 45 and 4st, whereby the speed of the shaft end connected to the operating wheel will be increased, and the propeller will be driven at a. higher rate of speed than the ate of speed of the wheel 30. Two pr'opellers may be arranged on the boat as shown in Fig. 8, in this figure the beveled gear 26 is mounted on a shaft 47 having two propellers 48 arranged thereon, which would be driven in a common d rection by the rotation of the drive shaft 29. j

'When the passengers are seated in thecar 18 they will not'be in danger of being drowned by the water surrounding the boat nor in danger of. being seriously tossed about by the waves. Should it be desired.

to holdthe car 18 against movement ofthe shell 1 the hooks 49 of the said shell are connected to screw {eyelets 50.

Having described our claim 1. In a life saving device, the combination with a shell, of means for supporting passengers in vertical positions within the shell, a transparent end for the shell, a rod extending through theend, a water spreader journaled on the shell and the rod and means for propelling the shell.

2. In; a life saving device, the combination with a shell of tracks secured to the inner wall thereof, a car having wheels engaging the tracks adapted to rotate freely on said tracks, an end wall for the shell adapted to rotate thereon, an annular packing device adapted to water seal the connection be tween the end wall and the shell, a ventilating tube connected with the interior of the shell and. "car projecting through the end wall and-above the shell, a-hood for the ventilating tube having its lower portion provided with an upwardly turned flange ha ving its edge inwardly deflected, a member in the hood comprising a flange depending over the hood flanged portion and outwardly deflected over said portion to form a passage for air there-between, a support secured to the lower part of the ventilating tube, a rudder having slidable connection with the support, a pivot securing the rudder to the end all. and an angular operating rod havingsliding connection with the rudder extending within the shell.

3. In a life saving device, the combination with a shell, of means for v up mrting passengers within the shell, :1 ventilating tube for the shell, an'e-nd wall rotatably connecting the tube'tdvthe shell, a U-shaped support depending from the ventilating tube, a rudder having slidable connection with invention we the U shaped support. a pivot connecting tatable on the shell, and a water spreader connected at its front end to the shaft and at its rear end. to the band.

In testimony whereof we atliv our signe tures, in presence of two witnesses.
